>When I use a hot key to change pages in a pageframe, I see that the focus stays on the top part of the tabbed page and does nto go to the first textbox. How do I automatically get the hot key to also move the focus to the first textbox on the page?

Loop through the controls on the page (through the Controls collection) and SetFocus to whatever control that has a TabIndex of 1 and is Enabled and Visible.

FOR EACH oCtrl IN this.Controls
  IF PEMSTATUS(oCtrl,"TabIndex",5)
    IF oCtrl.Enabled AND oCtrl.Visible AND oCtrl.TabIndex=1
      oCtrl.SetFocus()
      EXIT
    ENDIF
  ENDIF
ENDFOR
